§  10.320   Provider alert gateway requirements.

   This section specifies the functions that each Participating Commercial
   Mobile Service provider is required to support and perform at its CMS
   provider gateways.

   (a) General. The CMS provider gateway must provide secure, redundant,
   and reliable connections to receive Alert Messages from the Federal
   alert gateway. Each CMS provider gateway must be identified by a unique
   IP address or domain name.

   (b) Authentication and validation. The CMS provider gateway must
   authenticate interactions with the Federal alert gateway, and validate
   Alert Message integrity and parameters. The CMS provider gateway must
   provide an error message immediately to the Federal alert gateway if a
   validation fails.

   (c) Security. The CMS provider gateway must support standardized
   IP-based security mechanisms such as a firewall, and support the
   defined WEA "C" interface and associated protocols between the Federal
   alert gateway and the CMS provider gateway.

   (d) Geographic targeting. The CMS provider gateway must determine
   whether the provider has elected to transmit an Alert Message within a
   specified alert area and, if so, map the Alert Message to an associated
   set of transmission sites.

   (e) Message management --(1) Formatting . The CMS provider gateway is
   not required to perform any formatting, reformatting, or translation of
   an Alert Message, except for transcoding a text, audio, video, or
   multimedia file into the format supported by mobile devices.

   (2) Reception. The CMS provider gateway must support a mechanism to
   stop and start Alert Message deliveries from the Federal alert gateway
   to the CMS provider gateway.

   (3) Prioritization. The CMS provider gateway must process an Alert
   Message on a first in-first out basis except for Presidential Alerts,
   which must be processed before all non-Presidential alerts.

   (4) Distribution. A Participating CMS provider must deploy one or more
   CMS provider gateways to support distribution of Alert Messages and to
   manage Alert Message traffic.

   (5) Retransmission. The CMS provider gateway must manage and execute
   Alert Message retransmission, and support a mechanism to manage
   congestion within the CMS provider's infrastructure.

   (f) CMS provider profile. The CMS provider gateway will provide profile
   information on the CMS provider for the Federal alert gateway to
   maintain at the Federal alert gateway. This profile information must be
   provided by an authorized CMS provider representative to the Federal
   alert gateway administrator. The profile information must include the
   data listed in Table 10.320(f) and must comply with the following
   procedures:

   (1) The information must be provided 30 days in advance of the date
   when the CMS provider begins to transmit WEA alerts.

   (2) Updates of any CMS provider profiles must be provided in writing at
   least 30 days in advance of the effective change date.
